Here are 5 things to try to improve cellular signal:
Go outside or into a different room
Move outdoors or to a different room where your device isn’t impacted by the possible physical limitations within the building. Man-made structures around us often act as barriers. This includes materials such as:
- Concrete
- Masonry
- Drywall
- Insulation
- Electrical wiring
- Coated glass
- Vinyl siding
- Stucco
If you have a strong signal when you step outside but a weak signal as soon as you’re indoors, then the building’s materials are likely interfering with your coverage.
Removing the case
According to research, some phone cases can decrease cell signal strength by 90%. Depending on how a phone case is designed, it can fully or partially block your phone’s antenna.
Try VoWiFi Calling
If you have good Wi-Fi coverage in your home and you have a VoLTE capable device; enabling VoWiFi Calling can help when you are in an area where the cellular coverage is weaker by using the WiFi to boost your connection to the cellular network.
Check for software updates
Outdated software on your device may be the cause of coverage issues. To ensure your phone is performing at its best, maintain a full battery along with the most recent software and firmware updates. Older phone models may not have the hardware to access faster, stronger networks, so an upgrade is also a possibility. It is best to be connected to Wi-Fi when checking for software updates to avoid depleting your data plan.

Cell Boosters
If you are located at the edge of a cellular signal's range, this is considered "fringe" coverage. This is the area where geographical landscape and other sources of interference will cause the signal to be low. A cell phone booster is a device that takes an exterior cellular signal, even one that is faint, and amplifies it to improve the connectivity inside your location. So even if you only minimal service outside of the house a booster can help improve service.
